Product details
Overview
DMN2041UVT-7 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in TSOT26 package, rated for 20V VDSS, 28 mΩ RDS(ON) @ 4.5V VGS, and 5.8A continuous drain current at +25°C - optimized for high-efficiency DC-DC converters and LED backlighting power stages.
For engineers reviewing the DMN2041UVT-7 datasheet, DMN2041UVT-7 pinout, DMN2041UVT-7 application, or DMN2041UVT-7 equivalent, key selection criteria include low-voltage gate drive compatibility (1.8V–4.5V), junction-to-ambient thermal resistance (87°C/W on 1"×1" 2oz Cu), and dual-channel integration for synchronous buck or load-switch topologies.
Technical Context
This dual N-channel MOSFET employs trench-gate silicon technology to achieve low RDS(ON) while maintaining fast switching (tF = 17 ns, tD(OFF) = 32 ns) and low gate charge (Qg = 9.1 nC). Its symmetric channel pairing supports matched conduction in half-bridge or dual-phase configurations.
The device operates across –55°C to +150°C junction temperature range with robust gate oxide integrity (±8V VGSS) and low input capacitance (Ciss = 689 pF), enabling stable operation in compact, thermally constrained power management ICs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 20 V - Supports 12V/15V rail systems with 20% margin against transients |
| RDS(ON) @ 4.5V | 17–28 mΩ - Enables <100 mW conduction loss at 5A in compact PCB layouts |
| ID (continuous) | 5.8 A @ +25°C - Sustains >4.6 A at +70°C ambient without derating in standard FR-4 |
| Qg | 9.1 nC - Reduces gate driver power demand and enables >1 MHz switching in buck regulators |
| RθJA | 87 °C/W - Achieved on 1"×1" 2oz copper; defines thermal headroom for 1.44 W max dissipation |
| Ciss | 689 pF - Limits Miller effect during high-dV/dt transitions in synchronous rectification |
| VGS(TH) | 0.4–0.9 V - Ensures reliable turn-on with 1.8V logic-level controllers and battery-backed supplies |
Pinout & Package

Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) @ 2.5V VGS | 32 mΩ - Enables direct drive from Li-ion battery (2.8–4.2V) without level-shifting |

| Fast body diode recovery | VSD = 0.7–0.9 V @ 2.25A - Minimizes reverse conduction loss in synchronous rectifier mode |
| Thermal stability | RDS(ON) variation <1.5× from –55°C to +150°C - Maintains predictable current sharing across temperature |
| Moisture sensitivity | Level 1 per J-STD-020 - No bake required before reflow; simplifies SMT assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2041LVT-7 | Same die, but TSOT26-6 with different marking and qualification level (non-automotive) | No AEC-Q101 qualification; not suitable for automotive-grade designs requiring PPAP | Select when cost-sensitive industrial use requires identical electrical specs without automotive traceability |
| AOB2041L | Higher RDS(ON) (35 mΩ @ 4.5V), larger TSOP-6 package (3.05 × 1.65 mm), higher Qg (12.5 nC) | Lower switching efficiency above 1 MHz; requires larger PCB footprint and more gate drive power | Choose only if legacy board layout mandates TSOP-6 mechanical compatibility over performance |
Compared with DMN2041UVT-7, DMN2041LVT-7 offers identical electrical behavior at lower cost but lacks automotive documentation, while AOB2041L trades efficiency and size for broader distributor availability - making DMN2041UVT-7 optimal for space-constrained, high-frequency power management where thermal and gate-drive efficiency are critical.

FAQ
Is DMN2041UVT-7 qualified for automotive applications?
No - DMN2041UVT-7 is not AEC-Q101 qualified. Diodes offers the pin-compatible DMN2041UVTQ-7 variant for automotive use, which undergoes additional stress testing, PPAP documentation, and IATF 16949 manufacturing controls. The UVT-7 version is intended for industrial and consumer power management only.
What is the maximum safe operating frequency for DMN2041UVT-7 in a synchronous buck converter?
Based on its 9.1 nC gate charge, 17 ns fall time, and 689 pF input capacitance, DMN2041UVT-7 supports stable operation up to 2 MHz in well-designed layouts with low-inductance gate loops and adequate gate drive strength (≥1 A peak). Efficiency drops above 1.5 MHz if gate drive voltage falls below 4.0V due to increased switching losses.
Can DMN2041UVT-7 be used in a high-side configuration?
Yes - both channels support high-side switching when paired with appropriate gate driving circuitry (e.g., bootstrap or charge-pump controller). However, the device lacks integrated level shifters; external gate drive voltage ≥ VIN + 4.5V is required to fully enhance the high-side MOSFET and maintain low RDS(ON).
Does DMN2041UVT-7 require special PCB layout considerations for thermal performance?
Yes - to achieve the 87°C/W RθJA rating, the datasheet specifies a 1"×1" FR-4 board with 2 oz copper on one side and minimum recommended pad layout (including thermal vias under the exposed drain pads). Without this layout, RθJA degrades to 113°C/W, limiting continuous current to ~3.8A at +70°C ambient.
